Materials needed:
Different sizes of balloons
Different sizes of straws
Stopwatch
String (kite, fishing line, thread)
Tape (scotch, duct, masking)
Paper and pencil (for recording)

Objective: To get your rocket to go the farthest and the fastest.
Directions:
1.) Students will be put into groups of three to four.
2.) Students will use materials provided and can only use a maximum of two balloons. Two balloons can be taped to each other or just one can be used. Each group will determine which materials they will use that will give them the best results. If you pop a balloon, you may not get another (be careful not to blow them up to much or you will only be down to one).
3.) Each group will determine what type of string you will launch your rocket on. There will be 30 feet of each type of string provided by the teacher.
4.) Once each group is ready to launch the teacher will have one person on the end of the string holding it taught while the teacher is on the other end holding the rocket (balloon). There will be a person who starts the stopwatch at the teacher’s request. Once the balloon stops (air is out of balloon) then the stopwatch stops and that time is recorded. A person also needs to measure the distance (in feet) attained as well as record it.
5.) Students will be able to launch their rockets twice and take the best results.
6.) Mark your results on the table
Speed is calculated by taking distance divided by time
S= d/t
